Abstract

Multi-user equipment approved in grant 2015/17763-2: Triple Quadrupole Gas Chromatograph-Mass Spectrometer (GC/MS/MS) Coordinator: Márcia Caruso Bícego. The evaluation of organic compounds in environmental matrices such as biota, sediments, and industrial wastewater is a difficult task, since the amount of natural and man-made compounds turns out to be a complex mixture. To differentiate and quantify specific compounds, it is necessary to have high sensitivity and selectivity equipment to avoid mistakes. The chromatograph coupled to mass spectrometer (GC / MS) has been a widely used technique for analysis of volatile organic compounds and semi-volatile. However, due to coelution and similarity of some compounds, in addition to low concentrations, it is necessary to acquire a more sensitive and selective tool. The equipment to be purchased is a gas chromatography coupled to a mass spectroscopy system with triple quadrupole (GC/MS/MS) and is more sophisticated than GC/MS and it is one of the most suitable methods for the identification and quantitation trace levels analytes in complex matrices. In this technique, the molecules of interest are fragmented twice. First molecules are fragmented at 70 eV and so the system is able to isolate and fragment a selected fragment again by generating a spectrum obtained from this ion. The machine uses a wide wave frequency range for the isolation of the ion. The analysis in tandem provides higher selectivity and sensitivity of the GC/MS system. The system GC/MS/MS triple quadrupole requested allows quantification levels unachievable by GC/MS systems. His new source of electrons Ionization (EI) has lower detection limits and therefore it is possible to detect very low levels of trace analytes. The applications are numerous and the most common mainly include environmental assessments, food analysis, the oil industry, pharmaceuticals, etc. The analyses involving these devices are more selective and sensitive and may be faster and cheaper, since it can eliminate processing steps. Therefore this equipment could give a significant improve on research not only the Oceanographic Institute, and for the entire scientific community of the University of São Paulo and the State of São Paulo.
